Is the B140HAN01.3 panel that good for a 14" display? I feel that I am not appreciating my modded T430s that much if this is true.

I would of though there were better color accurate panels by now.

If you know of a better one, I would hazard a guess that any 14" display will work. Some non-Lenovo ones might have screw hole alignment issues. FWIW, even though my B140HAN01.3 had the Lenovo FRU sticker on the back, its EDID is showing as AUO133D rather than LEN40A3 and yet the brightness controls work anyways.

The dimensions are identical to the T470, I might bet that the T25 keyboard would be compatible. When they publish the T480 FRU BOM we can check if the T470 and T480 keyboards have the same FRU (but this would only be slightly indicative).

You get an 8th gen CPU and slightly faster RAM, while losing the nVIDIA GPU. "Worth it" is of course in the eye of the beholder.

Have people demonstrated it's *not* compatible with the T470? I guess that would certainly be informative. But I also guess there might not be much incentive for someone to try it, unless they have both systems handy.

It definitely seems to me that the T470 and T25 are very similar systems. They share the same BIOS files for example. I was able to use the T470 3-pin LCD cable to get a non-touch panel working on my T25.
